use of the filibuster, but other methods of instruction with bill clinton's who reached out all the time. so i think that's a factor, but a minor one. i think kerry reads use of filling the amendment tree, partly this is chicken and egg, but is been done too much and that could result in at least some protests and willingness of some senators on his side you might not otherwise join some of these filibusters to do so. but it had much more to do with a concerted party strategy, which i think it's really the first time we've seen it. >> i think there's two separate issues. one obstruction on nomination and to come the obstructions on the legislative. on the nomination site, it is true you see these judge votes and they happen to go 992.one. it's important to remember what we are talking about. the alternative to that is to move it by unanimous consent. this is not like the house for thursday though. the member objects unanimous consent because they do not want to vote or don't want to be forced to vote for a judge with whom they may disagree but support, they say i will have the roll
